A spokesman for the council would not confirm whether all the firms listed by Cllr Strangeway were being invested into.

But the Post understands that Brough-based firm BAE Systems (British Aerospace), forms part of the investments portfolio.

The spokesman said: “The East Riding Pension Fund invests in a diverse mix of asset types and sectors in order to spread risk and ensure the best possible return for the fund.
“It is not uncommon for pension funds across the country to invest in the aerospace and defence sector and the amount invested in this sector by the East Riding Pension Fund accounts for less than one per cent of the fund.”

Cllr Strangeway says he has requsted a vote to stop investing in arms which will take place in March 2017.
